I have about that vision without correction.
Which is why 20/200 is NOT the definition of legally blind. I believe the definition of legally blind now hinges on how bad your vision is after correction. For example, prior to having PRK laser surgery (like lasik but different) a few years ago, my vision was HORRIBLE. It was immeasurable in the 20/whatever scale... it would have been something like 20/800 or something. Over 12 diopters of correction. But with contact lenses, I was correctable to 20/15. So I wasnt' legally blind. The 20/200 definition of legally blind changed back in the 70s. So in the 1970s, I was legally blind, but the changed that definition as advances in lense technology came into being.
And while it sucks from a practical standpoint, we cannot afford to be "snobs" at who is ALLOWED to carry... Shall Not Be Infringed isn't a convenience that we get to judge and decide WHO shall not be infringed, it means EVERYONE. We can only hope and pray fervently, and use our FIRST amandment rights to SPEAK OUT and TELL people that they need to get training.
